This is really a random comment, but I'm currently loving having no window coverings. We do have custom blinds fit into every window, but we keep them pulled up almost all the time. There is no curtain to be found anywhere in my house. It was originally this way because my husband bought the house and lived in it alone before he met me, and he was not into decorating. But after I moved in and finally painted the builder white walls, I realized that I really loved the clean look. My windows are very similar to yours - 6 over 6 divided light, with white trim. (My trim might be very slightly wider than yours - hard to tell.) My instinct used to always be to put up curtains, but now I've moved away from that. As long as your trim is good, having no curtains results in a very clean look. You also don't have to worry about coordinating with furniture, wall color, etc., and about what length to use on windows that don't go all the way to the floor. And you get as much natural light as possible. If I were you I would actually remove those drapes. You've got a great clean look throughout the kitchen, without window coverings. If you need privacy, you could fit wooden blinds inside the windows. It's hard to tell exactly what color the walls in the living room area are - I think they are probably more the soft creamy yellow that it appears in the last photo, and not the pink/peach it appears in other photos. If it's the same as what is in the kitchen, then I think that color is actually very good. You might want possible want something slightly more taupe-y for the living room, but since it is open to the kitchen, you'll have to be careful about the color. I know, off-topic... it's just that I have been looking at a ton of real estate photos lately (might put our house on the market in a couple years, and I'm interested in what the market is like) and curtains always seem to ruin things. They seem to be the most taste-specific things and the things that most easily seem to ruin rooms. It seems like EVERYONE immediately puts up curtains, but they're often just messy and don't really do anything to enhance the room. Yours are actually pretty good - very pretty color - but they limit you a bit. The "correctness" of that length on windows that size is also debatable. I've read that you should make the drapes go to the floor, but I've also seen a supposed "egregious real estate photo" which was flagged specifically for having drapes fitted like that. BTW, would you keep that rug (which I really like)? Could you look closely at it and maybe pull out a color which doesn't immediately jump out at you, and use that on the wall? That would pull everything together. Just so you know, my furnishings are similar in color scheme to yours, and my walls are a similar yellowish, with one wall (which runs into the kitchen) being sort of a sage-y olive-y green. I don't know that I love the yellow, and the green is too dark to do on all the walls, but something in that family, just lighter, would work on all the walls. You might go for a light grey with an undertone of green.

Would likely prefer twin cabinets rather than twin "dressers" -- it is a foyer rather than a bedroom. You could still add matching mirrors and lamps. https://www.overstock.com/Home-Garden/Media-Bookshelves/featured/2031/subcat.html?featuredproduct=20543566&featuredoption=15590708&kid=9553000357392&track=pspla&ci_src=17588969&ci_sku=17360261-000-000&cnc=US&cid=271143&type=pla&gclid=EAIaIQobChMI9ZSekYmu2wIVy16GCh06XAL4EAQYAiABEgJlgvD_BwE&gclsrc=aw.ds&dclid=CIaf0paJrtsCFYnH4wcdJ4UHWw

Why did you ask for help just to ignore sound advice? What you have, even so far, won't be good in the long run. You will almost certainly have moisture problems between the bed and the wall. Besides mold problems, you are also looking at a bed frame that will rot. Hugelkultur and branches all rot and then occupy less space and aid your frame in rotting.. Without enough space/air flow under the bed, the frame will rot there too. I would advise you to remove what you have done. Line the bed with waterproof membrane and put a few drainage holes only on the bottom at the front. You really only need landscape cloth to stop your soil from leaking out of the drainage holes. If you want to use up space, the best thing to use would be rocks, stones, chunks of brick or chunks of concrete with landscape cloth over top (so your soil doesn't sink into the spaces). This will allow better drainage.

Regarding your question about laying something over the marble, in our last home the previous owners laid ceramic over ceramic and we lived there for over 25 years - no cracks. It will be a pain though for anyone down the road who is updating, but you could ask a pro to be sure (will need a transition piece at doorways). The area where closet was will have to be filled in and very level. If it were me, I’d bite the bullet and remove the marble and try to match up to your wood floor or use a more casual, rustic feel. You may look back and wish you had, especially if the marble looks patched.
